Few simple concepts regarding artificial
eyes in anophthalmic
patients
Any eye removal necessitates orbital implantation
•Why?
Primary orbital implants in retinoblastoma: DOI: 10.1111/aos.12915, 10.1371/journal.pone.0121292
Any eye removal necessitates orbital implantation
Anophthalmic Socket Syndrome:Loss of volume,Deepening of upper Lid sulcus,Shrinkage of fornices
Any eye removal necessitates orbital implantation
(!) Inability to insert an artificial
eye in the long term

Upon completing the surgery – put tetracycline ointment
and a big conformer to stretch the conjunctival fornices. Apply crape
bandage for 24 to 72 hours or perform temporal
tarsorrhaphy.•Why?
Perform Tarsorrhaphy at the End
Severe chemosis in the postop days after evisceration with orbital implant
Counsel the patient accordingly preoperatively and postoperatively (What?
Why? What’s next?)
•Why?
Counsel properly!
She was not offered an artificial eye before the removal. She has got lower lid ectropion and shallow fornices instead!
Fitting of the artificial eye: after 6-8 weeks
Artificial eye will move naturally only in
conversational distance (not able to deviate to the
extreme gaze positions)
Patient should be taught how to insert and remove the eye (devote separate time, quiet
room and a mirror)

Notch is superonasally!
Patient should be encouraged to minimize handling the
artificial eye.
No daily removal and cleaning is necessary.
Lubrication may improve comfort (no tap water!
Ringers, Saline or Artificial Tears may work well instead,
packed in the eyedrops bottles)
There is only one eye now. Encourage using the
protective plastic glasses.
Evaluating the socket of anophthalmic patient:1) Socket is fit or infmalmed?2) Lower lid is healthy or lax?3) Can the patient blink naturally?4) Any lagophthalmos?5) Are the fornices deep enough?6) Giant papillae of upper tarsal conj?
Evaluating the prosthesis1) Artificial eye is well centered?2) Horizontal symmetry?3) Equal prominence?4) High gloss, wet shine?5) Scratches, debris of the surface?6) Moving naturally within 10-15
degrees?
One artificial eye should serve for 6-8
years.Easily gets damaged while dropped down.Advise annual check
up.
